The Sun Hydraulics FTDALCN (Material Number: FTDALCN) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve features normally closed ports 2 and 3, with pilot pressure at port 1 opposing the internal spring to create a variable metering orifice between ports 2 and 3. This configuration allows for partial self-compensation as load pressure changes. The dual path design includes double port areas at ports 2 and 3, enhancing its flow management capabilities. For applications requiring pressure compensation, the valve can be paired with an external modulating logic element such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits, offering improved accuracy across a broad range of flows and pressures. The FTDALCN model incorporates Sun's floating style construction to minimize potential binding issues due to installation torque or machining variations. It has a capacity of up to 30 gpm (120 L/min) and operates effectively with a maximum operating pressure of 5000 psi (350 bar). The valve requires a minimum pilot pressure of 80 psi (5.5 bar) to shift and reaches full shift at rated flow with a pilot pressure of 300 psi (20 bar). Ports 1 and 4 should be limited to pressures not exceeding 500 psi (35 bar), as pressure at port 4 directly opposes that at port 1. The optional 'L' control offers stroke adjustment to limit maximum flow, providing users with enhanced control over hydraulic operations. With minimal leakage and low hysteresis, this valve is suitable for applications demanding reliable performance under varying conditions. Its design ensures accurate control by maintaining a constant pressure differential across the valve, making it an ideal choice for precision-driven hydraulic systems.

This valve is a 2-way, 2 position, proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice between port 2 and 3 that is proportional to the pressure at 1. The force balance of the flow forces, spring and pilot pressure results in a degree of partial self-compensation as the load pressure changes.
Pressure at port 4 directly opposes pressure at port 1.
The valve uses a dual path design. Ports 2 and 3 incorporate a double port area.
- These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
- The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
- The optional L control is a stroke adjustment that limits maximum flow.
- Ports 1 and 4 should be limited to 500 psi (35 bar).
- Pressure at port 4 directly opposes pressure at port 1.
- Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
